WATCH: Officials with Charleston Water said divers had to be sent down in complete darkness and search with their hands to find and clear a massive glob of "flushable" baby wipes this past week after it clogged parts of the sewer in Charleston, S.C.

A massive glob of “flushable” baby wipes clogged portions of the Charleston, S.C., sewer system, forcing divers to swim through nearly 30 metres of raw sewage to clear the obstruction.

Officials with Charleston Water said divers had to be sent down in complete darkness and search with their hands to find and clear the obstruction.

Then we sent divers 80-90 feet deep into the wet well/raw sewage to search in complete darkness with their hands to find and identify the obstruction. As we expected, they came up with these large masses of wipes in their first two loads, with more to come. pic.twitter.com/XcmZXf9ECF

“As we expected, they came up with these large masses of wipes in their first two loads, with more to come,” Charleston Water tweeted, along with photos of a massive heap of toilet wipes. “They also found a baseball and a big piece of metal. Don’t flush stuff like this. Joking of course, but you should only flush #1, #2, and toilet paper.”

Speaking with the Charleston Post and Courier, a water official said other items including feminine hygiene products, string, hair, makeup pads and kitchen grease add to the clogging problem.

They also found a baseball and a big piece of metal. Don't flush stuff like this. Joking of course, but you should only flush #1, #2, and toilet paper. The photo looking down into a pool of wastewater shows many other non-flushables. We made this pic low-res for your benefit. pic.twitter.com/fInq5YWU5a

“It boils down to the fact that ‘flushable’ wipes simply are not flushable. They may degrade over time and they may go down your toilet, but they certainly will block up the plumbing in your home, and wreak a lot of havoc in our system, so we would really appreciate any change that people could make,” a Charleston Water spokesperson told WCIV News.
